Specification of Letters Patent.

To all whom it but concern.-

Be it known that 1, WILLIAM (JYRUs SHINER, a citizen of the UnitedStates, residing at Catasauqua, in the county of Lehigh and State ofPennsylvania, have invented certain new and useful Improvements inRotary Kilns, of which'the following is a specification.

. eating with the kiln, a conveyor arranged in the base communicatinswith the chamber. and terminating in the kiln, and a bin con-' nected bythe conveyor with the kiln, all enibodying main features of my saidinvention; and Fig. 2 is a-siniilar view of the stack at a right angleto Fig. 1.

Referiing to the drawings, 3 is a rotary kilntube, which is supported inan inclined position and adapted to be rotated by means not shown." Inorder to connect the kilntube 3 directly with a stack, the sameterniinates in an opening 5, arranged in the front wall 6 ol the base 4thereof, in which the kiln freely rotates. In addition to receiving theend of the kiln-tube 3 the base 4 is provided with a chamber 9',arranged directly below the flue 10 of the shaft 8 of the stack, andwhich communicates with the kiln-tube 3. The lower portion of thechamber 9, at the sides parallel to the kilntubo 3, is formed withdownwaWily-inclined walls. 11, which terminate in a conveyor 1'2,located in the base i and preferably arrirnged in the verti-v calcentral axis of the base a, shalt S, and kiln-tube 3 for a pulpesc to bepresently more fully explained. The casing 13 of the conveyor 12 isprovided within the chamber 9 with an oblong opening 14, which isarranged in alinement with the inclined walls 11 thereof. The conveyor12 passes through the Wall 7 of the base 4 and beyond the same isconnected with a bin 16, which communicates therewith by an opening 15,arranged in the as sing 13.

l The bin 16 serves as a storage-receptacle for raw material to betreated in the kilntube 3c0nsisting, for instance, of lime, cement,rock, &c.which by means of the conveyor 12, when rotated by a pulley 18,is con ducted through the base 4 of the shaft 8 directly into thekiln-tube 3.- The kiln by hein rotated and held in an inclined position,wil conduct the raw material fed into the same toward the lower end,(not shown,) from which it is discharged. During the travel of thematerial through the kiln-tube 3 the same is subjected to an intenseheat generated and conducted through the kiln-tube 3 by means not shown.The gases of combustion of the fuel and those arising from material, aswell as the dust or fine particles of such in the kiln due -tocontinuous" eleva-.

tion and descent caused by the rotation thereof, are withdrawn therefromby the draft induced by the shaft 8 through the chamber 9 into the flue10 thereof. I The dust or fine particles thus removed from the kiln-tube3,

with the gases, are drawn into the flue of the shaft 8, accumulatil? onthe walls thereof, from which they final y drop by gravity back into thechamber 9. The inclined walls 11 thereof aid in conducting the dust orfine particles into the conveyer 12, which return the same back into thekiln-tube 3. The conveyor 12 by being connected with the stor- 'age-bin16 will also conduct the raw material into the kiln-tube 3, therebyserving a double purpose.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a rotary kiln, a stack provided with a base having a chamberadapted to receive and to retain matter drop ed from the stack, akiln-tube connected Wit the base and ter urinating with its interiorportion. slightly below the chamber thereof, and movable means i orpositively conductim the descending m attcr from the stack-flue irectlyinto said kiln.

2. In a rotary kiln, a kiln tube, a stack having a base provided with achamber, the walls whereof parallel to said kiln are downwardlyinclincdand terminate in a horizontally-arranged meeting portion, a casing 10--catcd in said base having an o oiling. arranged in alinement with theH10 med walls of the chamber and terminating in said kilnsignature inthe presence (if two subscribing tube, the inclined Walls of saidchamber Witnesses.

ada ted to conduct matter dro) in from r T the stack directly into saidcasin g ai id said WILLIAM C1 BUS 5 conveyer adapted to conduct thematter di- Witnesses:

rectly into said kiln-tube. GEORGE KOPP, In Witness whereof I havehereunto set my I R. L. WEAVER.
